I started with a Syma 107G, then the WL 911, MJX F645 F45. Then as I started looking for a more advanced Helicopter I saw on EBAY this lot for Esky 450 Cp V2 assortment and parts. But it said too were ready to go the rest needed minor repairs. OMG!!! everyone of them has been cannibalized. I might be able to get two of them together. I admit I had no clue what I was getting myself into, the seller did sound reliable, and I do have a lot of parts. (the FS-TH9X did not come with it) Trust me I been wearing out the how to's to try and figure this mess out. It is rather funny, you know what they say about hindsight. There is an upside I will probably and expert on repairing the ESKY 450 CP v2, by the time I am done. By the way anyone need any parts? I know about airplanes I won't be making this mistake with them. Thanks for looking I hope you got a chuckle Sam
